Neat Supra “B-series” differential crown wheel and pinion.

10:37 (3.70:1) ratio. A custom ratio perfect for cars with auto transmissions used for drag racing; would also perfectly suit cars using the V160/1 transmission who want extra acceleration; or cars with T56 conversions.

Suits larger B series 220mm diff that came in factory turbo cars – includes B02A, B02B, B03B, B04A and B04B.

Stronger than standard OEM gears. 9310 case hardened steel, profile ground after heat treatment.

We also make these in 3.36:1 ratio here which closely matches the OEM ratio but is much stronger.
